摘要

考虑海上大兆瓦风机复杂的运行环境，研制了一种带有金属弹性关节且轴孔平行的连杆联轴器。建立连杆联轴器整体有限元模型，对其关键部件进行了强度校核，分析了其在额定（最大）转矩下的各关键部件应力大小和分布特征；基于转矩载荷时序，结合联轴器材料

曲线，运用有限元分析软件，得到联轴器疲劳寿命；通过刚度测试试验、静态与动态性能试验及动平衡试验，得到联轴器的整体轴向、角向及扭转刚度，标定了打滑转矩，给出了转矩传递效率及动平衡等级。结果表明，该联轴器结构强度及寿命满足设计要求，且能达到预期打滑转矩效果；同时，转矩传递效率可达99.93%以上，动平衡等级不超过G1.0，联轴器性能满足大型海上风电机组使用要求。

Abstract

Considering the complex operating environment of offshore large megawatt wind turbines

a connecting rod coupling with metal elastic joints and parallel shaft holes is developed. The strength of its key components is checked

the overall finite element model of the connecting rod coupling is established

and the stress magnitude and distribution characteristics of each key component under rated (maximum) torque are analyzed.Based on the torque load sequence

combined with the coupling material

curve

and using finite element analysis software

the coupling fatigue life is obtained. Through stiffness tests

static and dynamic performance tests and dynamic balance tests

the overall axial

angular

and torsional stiffness are obtained

the slip torque is calibrated

and the torque transmission efficiency and dynamic balance level are given. The results show that the structural strength and life of the coupling meet the design requirements

and can achieve the expected slip torque effect; at the same time

the torque transmission efficiency can reach more than 99.93%

the dynamic balance level does not exceed G1.0

and the coupling performance can meet the requirements of large offshore wind turbines.
